Not only do linguistic terms sometimes appear in the titles of novels,
a few linguistic/semiotic/semiologic terms have become the names of
fonts (typefaces). They are:
Syntax - designed by Hans Ed. Meier (Zurich)
Symbol - designed by Aldo Novarese of (Turin?)
Signa - designed by Andre Guertler, Christian Mengelt, Erich
Gschwind (Basle)
Icone - designed by Adrian Frutiger (Paris)
Curiously, they are all more or less sans-serif (Signa has slight flares
at the terminals of its strokes, and Icone has pronounced flares that are
almost serifs).

More on the recent novel DR. SYNTAX by Michael Petracca. It
concerns a purloined volume of "DR. SYNTAX", which was bequeathed
to the protagonist, a grad student in English. The hero is not as
concerned with the volume itself, but with the dissertation notes
he has left inside. It's a humorous/bizarre little tale, worth
a read. It even has footnotes.
